The Bilderberg Group, a secretive confab of politicians, economists, academics, and business leaders, met in Watford, England, over the weekend, and the BBC's Sunday Politics show was on it. For the uninitiated, the segment started out with a short primer on Bilderberg and its fascination for conspiracy theorists.

The fireworks started when host Andrew Neil introduced his guests for the panel discussion: Alex Jones, the conspiracy-minded alternative-media mogul, and Times of London journalist David Aaronovitch, who has written a book debunking conspiracy theories. It was about as calm a discussion as you'd expect. (Watch above — the conversation starts at the 3:40 mark.)

As soon as Neil asks Jones about Bilderberg — Jones is leading a protest of the gathering — the American radio host starts off full bore about fluoridated drinking water causing bone cancer. After Neil steers the topic back to Bilderberg, Jones rails against the euro and big banks, then charges that "Bilderberg is heavily involved in the E.U. plan and helped hatched it, and it is a Nazi plan."

Neil tries to foster a discussion by asking Aaronovitch about Bilderberg, and Aaronovitch asks Jones why he's still alive if the New World Order is so powerful and deadly, and he is its main antagonist? Jones says he has been threatened, but "they" don't want to make a martyr of him. The rest of Aaronovitch's banter is buried under Jones' interruptions.

Neil has finally had enough, telling Jones to "shut it." That really sets Jones off, and Neil finally ends the segment telling Jones he is "the worst person I've ever interviewed," telling the viewers: "We have an idiot on the program today." With Jones still screaming in the background, Neil circles his finger around his ear in the universal "he's crazy" sign.

Everyone took to Twitter for their postmortems of the program:

If you thought that @daily_politics discussion on #Bilderberg was mad to watch, all I can say is that actually being there was even crazier.

This amazing piece of television is "funny, but it's also sad," says John Aravosis at AmericaBlog. "I don't know if Jones is considered left or right, but he's a good example of the crazy shock jock style that infests much of right-wing talk radio and talk TV in this country. And it is embarrassing to have him go on a show abroad [as] 'the American.'"
